Specification of Letters Patent.'

Patented Jan. 23, 1912.

Application led August 24, 1905. Serial No. 275,516.

To all whom it may concern:

Be it known that I, CLARENCE Voer, citizen of the United States lof America, residing at Berlin, in the Empire of Germany, have invented certain new and useful Improvements Relating to Needle-Holders for the Sound-Boxes of Talking-Machines, of which the following is a specification.

This invention relates to needle-holders for the sound-boxes of talking machines, and more particularly to needle-holders or stylus hars of the kind in which the insertion and securing of the needle is effected without the employment of screws or similar fastening means. For this purpose, lsuch needleholders are provided with clamping means, in which the needle is held by friction so as to be capable of beingfreely changed, additional spring pressure being provided if required. The needle is secured in its correct position by the pressure of the sound box on the record and the clamping 'means are preferably oppositely-located in the bore of the needle-holder, so thatI the needle is grasped and held at the upper vend by one and at the lower end by the other clamping means. It may be understood that the invention relates also to needle-holders havin in the usual manner screws for fastening the needle, eventually in combination with clamping places.

An important feature oi' the present invention consists in that a lateral longitudinally-extending f slot is provided in the needle-holder near the clamping means, through which slot the needle can be conveniently introduced into and removed from its operative position between the clamping means through thesides Iof the needle-holder, the said needle meanwhile moving parallel to its longitudinal direction'. This lateral insertion of the needle resents the advantage that, for the insertion and replacement of the needle, a mechanical device can lbe arranged whereby the needles are fed, mov# ing parallel to themselves, into the lateral slot in the needle-holder, in the contradistinction to the known .needle-changing devices in which the needles are moved along in the direction of their axes. The lateral insertion of the needle further presents the possibility of arranging the mechanical needle-changing device independently of the sound-box and of its carrier-arm and of thereby relieving the sound -box of the weight of the needle-carrying device. The needle-holder can be provided, on the side oppositeV to the inlet slot, with an additional slot which serves for the feeding out of the needles. This preferably takes place in such a manner that the new-needle introduced laterally into the needle-holder automatically pushes out the alreadv used needle still in the holder, at the other side.

A separate locking or holding device may, if desired be provided on the needle-holder, this device being constructed in such a manner that it holds the needle elastically in the normal position, but automatically opens by the lateral pressure when a needle is insertedand replaced. rThe locking or holding means for the needle when the needlesholder is made with two oppositely-arranged slots, is formed in such a manner that when inserting a new needle the previously used one ,is thrown out of the holder by a spring.

In the drawing, Figure 1 is an underside view of a sound-box which is pivotally attached to the sound-box arm and which has a needle-holder provided with clamping means and lateral slots, and which has a retaining spring for the needle. F ig. 2 is a side elevation corresponding to Fig. l. Fig. 3 is a side elevation of a sound-box and needle-holder`- with a lateral slot and spring, in combination with a device whereby the needles are fed out of a needle-magazine to the lateral'slot of the needle-holder. Fig. 4 is a plan'of this device for changing the needles, with the sound-box depressed. Fig. 5 is an oblique elevation looking from the front with the sound-box swung up, and with the needle-magazine and the needlechanging device in section. Fig. 6 is a rear elevation of the needle-changer. Figs. 7 to 9 show an example of construction of the needle-magazinein diHerent kinds of elevation, Fig. 7 being a side elevation with the front wall somewhat drawn up, Fig. 8 a front eleva't-iomand Fig. 9 a horizontal section of Fig. 7. Fig. 10 is a partial side elevation of a talking machine looking in the direction of the arrow A of Fig. 11. Fig. 11 is the plan corresponding to Fig. 10. Fig. 12 shows a sound-box with a needle-holder having two slots and an inserted needle in the operative position. Fig. 13 is an elevation of the sound-box looking toward the needle-holder. Fig. 14 is a transverse section on the line I-II, Fig. 13. Fig. 15 is a plan corresponding to Fig. 13. Fig. 16 shows the needle-holder in section and similar elevation to Fig. 13. Figs. 17-20 show diagrammatically and to an enlarged scale, how a new needle is inserted into the needleholder and the previously used needle removed. Figs. 21--23 are views of the needleholder with two slots, in combination with a needle-changer in different operative positions of the latter. Fig. 24 is the corresponding plan and Fig. 25 a side elevation.

In the form of construction shown in Fig. 1, the needle 2 is in the bore 1 of the needle-holder 3. rIhe bore 1 is not round in cross-section but is enlarged in the direction of the sound waves. The bore 1 is preferably bounded by inclined surfaces', between which the needle 2 can rest firmly. The clamping places can also form curved surfaces, so that the bore 1 has a substantially elliptical cross-section. The force required for the clamping of the needle is produced by the friction of the needle on the record 4 in the rotation of the latter in the direction of the arrow 5 `(see Fig. 3.) and by the working pressure, with which the soundboX is pressed against the record.

rIhe sound-box S is arranged in a known manner on the hollow arm 6 by means of a U-shaped connecting-piece 7 and a pivotal joint 9, so as to be capable of being moved up and down and so that the weight of the sound-box 8 produces the downwardly directed working pressure. Since the needle 2 rests obliquely on the record 4, the reactive force acts obliquely on the point of the needle 2.

The needle 2 can be introduced by hand I. into the bore 1 and be lheld fast until the sound-box is depressed to bring the needle 2 on to the record 4. After the depression of the sound-box, the needle can be released since the clamping of the needle is caused `by the lsupporting thereof on the record.

The needle 2 can also be held in the bore by means of a spring 10 (Fig. 1) until the said needle is placed on the record. Instead of the spring 10, any other well known means may be employed to prevent falling out of the needle before it is clamped.

In the form of construction shown in Figs. 1 and 2, the needle-holder 3 is provided on one side with a longitudinal slot 11 for the lateral lntroduction of the needle. The needle 2 is here inserted parallel to its longitudinal axis into the bore 1 betweenthe clamping places of the needle-holder 3. From Fig. 2 it can be seen that the needle lies in the clamping places of the needle holder, bounding the longitudinal slot 11 in such a manner that it cannot fall out sidewise. The spring 10, which prevents the falling out of the needle in the direction of its axis, also prevents it from falling out laterally since it presses the needle against the clamping surfaces bounding the slot 11. The small bolt 12 (Fig. 2) bears the spring 10, and simultaneously serves as an abutment for the upper end of the needle. The bore for the bolt 12 is of importance in the formation of the bore for the needle, since the former limits the axial bore 1 which receives the needle 2. The needle 2 can be inserted by hand through the lateral slot 11. The insertion of the needle from the side is considerably more convenient than in the axial direction. It permits, in a practical and convenient. manner, the insertion of the needles 2 by means of a mechanical device. For this purpose, in the device for changing the needles, the movable guide 13' for the slider 14 is provided with a longitudinal slot 15, in which a needle 2 can move transversely to the longitudinal direction of the slide. The longitudinal slot 15 is so arranged that it registers exactly with the slot 11 in the needle-holder 3, when the guide 13 is pushed up thereto. The slide 14 likewise moves in the slot 15 of the guide 13. It serves for feeding the needle lying in the guide 13 to the lateral slot 11 in the needle-holder 3. The slot 15 in the guide 13 is normally closed by a detent spring 16 in such a `manner that the needle 2 falling through a slot 17 in the guide 13 out of a needle-magazine 22 into the longitudinal slot 15 is held against the front surface of the slide 14. By this means, further needles 2 are prevented from falling out of the magazine 22 through the slot 17 into the guide. A second needle 2 fills up the slot 17; it

'takes the place of `the first needle after the latter has been insertedinto the needleholder 3, Fig. 5. A handle 18 is fixed in the slide 14. In the motion of the slide 14, the handle 18 takes with it the guide 13 by means of the tension of a spring 19 mounted Yon the guide, until 'the stop 2O thereof abuts against the frame 21 of the slide-device and of the needle magazine 22. Instead of the fixed stop 20, a stop 24 which is adjustable as desired by means of a screw 23 orthe like, can be employed. This adjustable stop is formed by the head 24 of the screw 23 for example. The screw-head 24 abuts against the end 25 of the base-frame 29 as soon as the movable guide 13 has bridged over the space between the needle-changer and the needle-holder. A set-screw 27 in the bearing standard 28 of 'the screw 23 serves to secure it in position after it has been adjusted. The guide 13 is guided on a baseplate 2,9 by means of the overlapping pieces 30. A spring 31, which engages with the handle 18 and the base-plate 29, returns the slide 14 and the guide 13 to their initial positions, acting in conjunction with the spring 19. On the side of the base-plate 29 is mounted a vertically arranged plate 32 which bears the magazine 22. This consists of a sheet-metal frame 33 with flanges 34, which grasp the vertical plate 32. A fastening device 34 serves for securing the magazine 22 to the plate 32. The front Wall 35 of the magazine, Which is fixed to the cover 36, is detachably connnected to the frame 33, so that the magazine 22 can be conveniently filled With needles When its outlet opening 37 is closed by a sliding shutter 38. The latter is provided at its front end-piece 39 with a hole 40 which, by the application of a lead seal, serves for protecting the filled magazine from being opened by unauthorized persons. A Weight 41 rests loosely in the magazine 22 and presses on the needles 2 in the magazine and the needles 2 are f'ed thereby with certainty to the outlet-opening 37. The magazine 22 presents the advantage that it can also serve as a storage-receptacle for the needles 2 instead of the needle-case otherwise usually employed.

An adjustable stop for the sound-box 8 is fixed on the sound-box-arm as shown in Fig. 4; this stop consistsof a screw7 42 with head and locknut. By means of this stop 42, the position of the swung up sound-box can be adjusted in such a manner that the slot 15 of the guide 13 and the longitudinal slot 11 of' the needle-holder 3 can register exactly with each other. A

An advantage of the transverse insertion of the needles consists l in that both the needle-changing device and also the magazine-,and adjustable stop 42 can be mounted on the box 43 of the talking machine (see Figs. 10 and 11) or on the sound-box-arm 6 see Figs. 3 and 4) and thus do not load the sound-box 8.

In the form of construction shown in Figs. to the arm 6 by means of a strap 44. On the carrier plate 45, in addition to the needlechanger 13, 14 and the magazine 22, there is mounted thc adjustable stop 42. ln the form of construction shown in Figs. 10 and 11. the needle-changer, magazine and adjustable stop are fixed to a stand 46 which, by means of a base-plate 47', rests on t-he box 43 of the talking machine. The stand 4G directly supports the base-plate 29 of the d needle-changer. On the stand 46 is fixed an arm 47 which, in addition to the adjustable stop 42, also bears a holding device-48 for the folded up sound-box 8. This holding device engages around the sound-box 8 (see Fig. 11) and holds it. fast by means of the spring-catch 49, so that it cannot be bent by the lateral pressure in the introduction of a new needle.

The needle-changer, in the form of con- 3 and 4, a carrier-plate 45 is secured struction shown in Figs. 3 to 11, is operated by actuating the handle 18 after the soundbox 8 has been placed against the stop 42 and the used needle 2 has been ejected, by pressing it with the finger to one side, out of the slot 11 in the holder.

l In the form of construction shown in Fig. 12, the needle-holder 50 is movably attached to the sound-box |51 by means of the flexible strip 52. The slot 53 for the introduction of the needles is extended through the whole needle-holder. In the slot are the grooves 54 for clamping the needles, While a spring 55 is arranged in such a manner that the needle in the slot 53 is pressed into a clamping groove 54.I For this purpose, the spring 55 is rounded at the the slot 53 so that the introduction of' a new needle on one side of the slot 53 is facilitated and at the same time the ejection ot' the old needle on the other side of the slot 53 by spring pressure is permitted. As can be seen from Fig. 12, the needle is held obliquely in the clamping grooves 54 in the slot 53, in the operative position of' the sound-box, by the weight of the latter, in

which position the spring 55 is pressed back` by the needle.

1When the sound-box with the improved needle-holder is combined with a needlechanger 56, as shown in Figs. 21 to 25, the slide 57 of the needle-changer,which effects the vintroduction of the new and the changing vof the old needle, must be. so guided in the needle-changer 56 by means of the pin 58 and its forward motion must be limited in such a manner that the newly inserted needle is not pressed out beyond the correct normal position on the holder. @n the slide 57 or on the pin 58, is mounted a handle 59 ywhich for the purpose of moving the slide 57, is operated by hand, or, in automatic talking machines, by an arm moved by the driving gear. Spiral springs 60 and 61 connected to the pin 58 tend to hold the slide always in the position shown in Fig. 21. On the frame of' the needle-changer 56 is detachably arranged the needle-magazine 62 with the needles 2. The guide 63, which is capable of 'being moved on the needlechanger frame and the slit G4 of which` receives the needles 2 from the magazine 62 and holds them ready for the slide 57, by reason of. the action of' the. spring 60, is carried along by the pin 58 of' the slide 57, which pin is guided in the longitudinal slot 65 of the guide 63, until its adjustable stopscreW 66 abuts against the frame of the needle-changer and prevents further motion. This takes place when the guide G3 is brought up to the needle-holder 50 and the insertion of the needle by the slide 57 is to begin.- The said slide is limited in its forward motion in that the pin 58 finally abuts against one end edge of end turned toward the slot 65,so that the ward motion of the slide 57 and of the guide 63l is effected, after-the insertion of the new -and the ejection of'the oldneedle, by the spiral springs 60 and 61.

rl`he sound-box 52, in the form of construction shown in Figs. 12 to 25, is also movably connected by the bent sound-boxarm 7 to the joint-piece 9 of the arm 6. A carrier-arm 67 secured to the arm 6 bears both the needle-changer 56 and also the adjustable stop 68, against which the soundbox 52 can rest when -in the position in which itis raised from the plate 4 (see Fig. 25).

The various positions ofthe needles in the insertion and changing thereof by means of the slide 57 are given in Figs. 17 to 20. In Fig. 17, a new needle 2 is in the guide 63 of the needle-changer 56 on the way to the needle holder 50,while the previously used needle 69 is still in the slot 53, z'. e., in the clamping grooves 54. The positions of the slide 57 of the guide 63 and of the needles 2 correspond substantially to those shown in Fig. 22. The guide 63 is stopped in its further motion by the striking of the screw 66 against the frame of theneedle changer. ln the position shownin Fig. 18, the slide 57 is pushed farther forward and the needle 2 has entered into the slot 53 in such a manner that it touches the old needle 69; the movable guide 63 is held fast as shown in Figs. 17 and 22. 1f now, according to Fig. 19, the forward motion of the slide 57 is continued, the fresh needle 2 forces 'the needle 69 out of the clamping grooves 54 at the same time overcoming the pressure of the spring 55. As shown in Fig. 20, the new needle 2 then enters the place of the old .needle 69 and the spring 55 flying back into the position shown in Fig. 17 causes the used needle 69 to be ejected from the slot 53 with a certain amount-.of force. Thereupon the return of the slide 57 and of the guide 63 takes place by means of the springs 60, 61. The needleholder provided withtwo slots is of lspecial importance for automatic talking machines with automatic mechanism for changing the plates. For talking machines of this kind, it is necessary that the insertion and ejection of the needles shall take place automatically. It is important that the needle shall be capable of being easily changed. The falling out of the needle can also be temporarily prevented by a recess turned in the-needle 2 or by thickening the end of the needle.

The construction of the needle-changer in its details can be varied as desired, similarly that of the needle-magazine. 1t is however always of importance that the outlet-openings of the magazine, the transverse slot and the longitudinal slot of the slider-guide shall be so arranged that the needle is moved parallel to its longitudinal direction as it is fed to the needle-holder.

- The needle-holder can be mounted in any desired manner, either as in Figs. 1 and 2, or as in Fig. 12.A It is however important that the needle-holder shall always be provided with a lateral longitudinal slot for the lateral insertion of the needle.

The invention is not limited to the combination of the needle-changer with a peculiar construction of needle-holder, since it is possible to provide a needle-holder having any other means therein for securing the needle.
